2014 update of the U.S. national seismic hazard maps
We held 8 regional and topical workshops across the U.S. to gather information for these maps. The maps were available to the public for comment during a 60-day period. A Steering Committee (9 experts) was assembled to review the inputs and results and provide additional insights. The maps have been presented at several professional meetings.
In this talk we discuss:
(1) CEUS, (2) WUS (outside California), (3) California, (4) Ground motion models
We discuss the hazard maps and hazard curves used in the building code. The maps in this presentation are for 2% probability of exceedance in 50 years on a uniform firm rock site condition (VS30=760 m/s). Maps are for 0.2 s (5 Hz) spectral acceleration with 5% damping.
We consider difference maps (2014-2008) and ratio maps (2014/2008).
